How to install Pandoc on ArchLinux

Does anyone have suggestions about how to install pandoc on Arch? I am trying to install pandoc-static from here: https://aur.archlinux.org/packages/pandoc-static/ , although it appears to be conflicting with my xmonad installation (I use xmonad as a TWM): [grease-lightning]/home/.../builds/pandoc-static$ makepkg -s ==> Making package: pandoc-static 1.15.0.6-1 (Sun Aug 16 23:18:48 PDT 2015) ==> Checking runtime dependencies... ==> Checking buildtime dependencies... ==> Retrieving sources... -> Found pandoc-static-1.15.0.6-1.tar.xz -> Found pandoc-static-1.15.0.6-1.tar.xz.sig ==> Validating source files with sha512sums... pandoc-static-1.15.0.6-1.tar.xz ...

Aborting... I am afraid of breaking my xmonad TWM if I force the reinstall. What should I do? Perhaps I should install Pandoc via sudo cabal install --global pandoc? If so, how should I install cabal? I was thinking that I should download it from here: https://www.haskell.org/cabal/download.html Any suggestions or recommendations are appreciated. I am also happy to clarify anything.
